The LF580 hybrid contains Sound Design Technologies' GK509 class A amplifier and a single input coupling capacitor. The extremely small size of the hybrid allows it to easily fit into many CIC and ITC applications.
Block A of the GK509 is a low noise inverting amplifier with an open loop voltage gain of typically 56dB. The closed loop gain is set by the ratio of input resistance to feedback resistance.
The output stage is a class A current drive amplifier. The current that flows in the transducer is the ratio of the 30mV reference voltage to the resistance to ground at pad 1 on the hybrid. With no external RE, the trandsducer current is typically 240μA, which makes it suitable for high impedance receivers.
